I'm going to assume there is no way to change how this feature works? My problem is the auto-rename feature works the opposite of what I expect. I prefer that the existing file be renamed and then the new file uploaded. This way it's backing up the previous file by renaming it and then uploading the new file. The way it works now is it renames the file I'm uploading and keeps the existing file, which really doesn't accomplish anything for me. Maybe I'm backwards but that's how I'm used to renaming working.
